TECHNICAL FIELD

The present invention relates to a novel heteroaryl compound having anti-diabetic activity or a salt thereof. More particularly, the present invention relates to a novel heteroaryl compound having an anti-diabetic activity, which improves insulin resistance and control the blood glucose level more safely, and/or being useful for treating or preventing metabolic diseases such as hyperlipemia, arteriosclerosis or metabolic syndrome. Further particularly, the present invention relates to a novel heteroaryl compound that regulates activity of peroxisome proliferator-activated receptor (PPAR) α, PPARγ, or PPAR α/γ.

BACKGROUND ART

The number of patients with diabetes mellitus has been increasing steadily owing to the recent change in the lifestyle. According to the research done in 1997 in Japan, it has been speculated that the number of people strongly-speculated as having diabetic mellitus is 6.9 million, and the number of people who can not be deniable the possibility of diabetes mellitus is 6.8 million. Most of the patients with diabetes mellitus in Japan are classified into type 2 diabetes mellitus, wherein the basal pathological conditions thereof are the reduced output of insulin and the insulin resistance, and medicaments against to each condition have been developed.

Although sulfonylurea (SU) agents, which is known from of old, have widely been used for improving the reduced output of insulin, the agents are known to have a risk of hypoglycemia as a serious side effect, and further to be apt to cause obesity.

On the other hand, thiazolidinedione agents are known as an insulin resistance improving agent.

Troglitazone was first put on market as a thiazolidinedione agent, but its sale was discontinued due to a serious hepatic damage. In Japan, pioglitazone has been clinically used at the present, but the heart failure due to the increase in circulating plasma volume was reported as a serious side effect thereof, and hence, Urgent Safety Information on pioglitazone was issued on October, 2000, which announced that pioglitazone needs careful attention to heart failure and edema. As to rosiglitazone, which has been widely used in Europe and the U.S., there are reported side effects such as infection of upper respiratory tract, anemia, edema, weight gain, etc. Thus, any thiazolidinedione agent having no concern regarding hepatic damage or side effects on the cardiovascular system has not been put on the market yet.

Thiazolidinedione agents are thought to exhibit anti-diabetic activity by activating PPARγ. It is known that PPAR has subtypes such as α, γ, δ(β), etc. Fibrate agents (e.g., clofibrate, fenofibrate, etc.), which are used as an agent for treating hyperlipemia, are considered to exhibit their pharmacological activities by activating PPARα. It has recently been reported that the insulin resistance is improved by administering a PPARα activator to animal models (cf., Journal of Biological Chemistry, vol. 275, p 16638, 2000), and there is a growing possibility where PPARα activators may show an effectiveness against diabetes mellitus as well as hyperlipidemia.

Many of compounds activating PPARγ or both PPARα and PPARγ such as isoxazolidindiones are reported other than thiazolidinedione agents (cf., Journal of Medicinal Chemistry, 43, p. 527, 2000), but the efficacy and safety thereof in the clinical field are not confirmed yet. At the present, PPARα agonists, PPARγ agonists, PPARα/γ agonists or PPARα/γ activation regulators having a good antidiabetic activity, are useful for treating or preventing metabolic diseases such as hyperlipemia, arteriosclerosis or metabolic syndrome and having high safety have been desired.

Many diabetic agents called PPARγ activation regulators (modulators, partial agonists) have been recently reported (c.f., Bioorganic & Medicinal Chemistry Letters, Vol. 15, p 357-362 (2005), and European Journal of Pharmacology, p 273-281 (2004)). There is suggested a possibility that these agents do not show side effects such as weight gain, edema or increase in heart weight observed in PPARγ full agonist such as pioglitazone or rosiglitazone, and have a good antidiabetic activity. The medicament having partial activity of PPARγ has been greatly expected to become a diabetic agent with high safety.

In addition, diabetic medicines having a pyrrole group in its structure have are known (cf., JP-A-2002-121186, WO 02/085851, WO 2004/048341), but the efficacy and safety thereof in the clinical field are not reported yet.

For example, when Ring Z is an imidazole, Compound (117) can be prepared, for example, by heating Compound (115) or Compound (116) with formamide at a temperature of 150 to 200° C.

(wherein R²⁰ and R²¹ are independently a hydrogen atom, a halogen atom, an optionally substituted alkyl, an optionally substituted aryl, an optionally substituted heteroaryl, or an optionally substituted thiol, and R²⁰ and R²¹ may be taken together to form a ring with the adjacent carbon atoms, and L⁴ is a hydroxy group, an amino, bromine atom, chlorine atom, etc.)

For example, when the ring Z is indole, Compound (121) can be prepared by heating Compound (118) and Compound (119) or compound (120) in acetic acid.

Compound (121) can be prepared, for example, by coupling Compound (122) and Compound (123) under palladium to give Compound (124) and then one electron reducing the compound under a reducing agent such as titanium chloride, etc.

For example, the ring Z is indazole and W⁴ is a single bond, Compound (126) can be prepared by reacting Compound (125) with sodium nitrite in the presence of an acid.

The acid includes, for example, hydrochloric acid, sulfuric acid, actetic acid, hydrobromic acid, trifluoroacetic acid, methanesulfonic acid, etc.

The solvent includes, for example, ethers such as ether, THF, dioxane, etc., aprotic solvent, such as acetone, dimethyl sulfoxide, N,N-dimethylformamide, acetonitrile, etc. These solvents may be used by mixing one or more thereof with water at an appropriate ratio. The reaction may also be carried out without a solvent.

The reaction temperature is selected from the range of about −20° C. to around of a boiling point of the solvent, preferably about −10° C. to around of a boiling point of the solvent.

In addition, when bromine or iodine exists for R² and R³ as a substituent on Ring Z, an aryl or a heteroaryl can be introduced into R² or R³ by Suzuki Coupling Reaction with an aryl borate or a heteroaryl borate (by the method disclosed in J.

Test 1 Evaluation of PPAR α or γ Agonistic Activity Construction of Reporter Plasmid

By inserting a gene fragment encoding the ligand binding domain of human PPARα (including amino acid residues 167-468) or a gene fragment encoding the ligand binding domain of human PPARγ (including amino acids residue 204-505) into a multicloning site of expressing vector pM containing DNA binding domain of yeast GAL4 protein (Clonetech), a vector plasmid for expressing a fused protein of GAL4 protein DNA binding domain and human PPARα or γ ligand binding domain was obtained.

As a reporter plasmid, pGL3-Basic Vector containing firefly luciferase gene (Promega Corporation) was used wherein Gal 4-responsive sequence UAS and rabbit β-globin promoter were inserted.

For the correction of transformation efficiency, a plasmid pβgal control (Clonetech) containing lacZ gene, was used.

Luciferase Assay

COS-1 cells were cultured in the phenol red free Dulbecco's Modified Eagles Medium (DMEM) (Gibco) supplemented with 5% activated charcoal/dextran stripped fetal bovine serum at 37° C. with 5% carbon dioxide. The COS-1 cells were plated at a concentration of 5×10⁴ cells/well into a 24-well plate, and were incubated overnight. The medium was replaced with a fresh medium supplemented without 5% activated charcoal/dextran treated fetal bovine serum. Further, the cells were transfected using Lipofectamine plus reagent (Gibco) with plasmids GAL4-PPARα- or γ-expressing plasmid (5 ng), the reporter plasmid (50 ng), and pβgal control (350 ng) per well. After incubation for 4 hours, the medium was changed with a fresh medium supplemented with 5% activated charcoal/dextran treated fetal bovine serum. Then, the compound of the present invention was added thereto in such an amount that the final concentration thereof is 0.1 μM, 0.3 μM, 1 μM, 3 μM or 10 μM. After the cultivation for 24 hours, the cells were lysed with a solution for cell lysis accompanied to the Luciferase Assay System (Promega Corporation). The luciferase activity therein was measured by a luminometer using the reagent for measuring luciferase which was also accompanied to said System.

The PPARα- or γ-agonistic activity was expressed as a relative activity where the luciferase activity in the well to which the vehicle (DMSO) was added as control was regarded as 1. The PPARα-agonistic activity and the PPARγ-agonistic activity at each 10 μM, and the maximum PPARγ-agonistic activity (%) of the compound of the present invention per the maximum PPARγ-agonistic activity (100%) of pioglitazone are shown in the following Table 1.
